Application, filed April 4, 1917. -Seria1 No. 159,763.

' Be it known that I, GARL H. BissnLL, a citizen of the United States,and a resident of Syracuse, in the county of Onondaga and To all whomitlmag concern:

State of New York, have invented a certain new and useful ElectricSwitch, of'

- which the following is a specification.

' away and partly in section, 0

This invention relates to electric switches, and has for its object aparticularly simple and efiicient mechanism by which a quickmake-and-break action of the switch is effected, which mechanism isparticularly simple and compact inconstruction, and

highly efiicient and durable in use; and the invention consists in thecombinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings, in which like characters designate corresponding parts in. allthe views.

Figure 1 is a side elevation of a switch embodying my invention, thecontiguous portion of a panel board base and the facing of a panel boardbeing also shown.

Figure 2 is a plan View, tp artly broken parts seen in Fig. 1, the coverof the panel board being omitted.

' Figure 3 is an end elevation of parts seen in Fig. 1. i

Figure 4 is a sectional view taken on line 44, Fig. 3.

This switch comprises, generally, a switch member, an operating member,and means for transmitting the movement of the operatin a quickmake-and-break action. Said members preferably move in oppositedirections with respect to each other; and said means includes a springshiftable by the operating member to tensionthe spring and to change thedirection of the force of the spring on the switch member, so that thespring acts panel board construction.

member to the switch member to effect direction on the switch member.

1 designates the panel board base; 2, the cover. or facing of the panelboard. 3 are fuse plug sockets in which fuse plu'gs are located. r i 5designates the base of the switch, which base is mounted on the panelboard base 1; and 6, 6 and 7, 7 are pairs of switch contacts mounted onthe base and connected respectively to pairs of conductor bars 8, 8 and9, 9, by means of screws 10, 10 and 11, 11, the bars 8, 8, 9, 9 beingmounted on the base of the panel board and connected in the electricsystem of the panel board.

12 designates the switch member which includes a 'bar of insulation andairs of knives or conductors 13, 14 couple or carried by the bar andmovable into and out of contact respectively with the terminals 6, fiand 7, 7'. 15 designates the operat:

.ing member which projects through the facmoves anti-clockwisev and viceversa.

The spring forming part of the means for transmitting the motion of theoperating member to the switch member is normally arranged upon one sideor the other of the axes of said members and is shiftable to the othersideof said axes, in order that the direction of the force of the springon the switch member may be reversed. The force of the spring is appliedin one direction on one side of said axes, and during the movement ofthe operating member in one direction, the spring is shiftedto the otherside of the axes; and during the movement of the operating. member inthe reversed direction, the force is applied in the oppo iiktle switchmember 12 is here shown as pivoted at 16 to the freeends of thebrackets-1T brackets 17 near the switch base 5, and a cap portion ofinsulation mounted on the arms 18 and being of such shape as to al- Waysclose the slot 20 in the cover 2 of the panel board in any position ofthe operating,

A suitable handle portion 21 1s mounted on the cap 15.

22 is the spring forming part of the mechmember,

anism for transmitting the motion of the operating member to the switchmember 12, the spring being connectedat its opposite ends respectively,to said members ,It 1s connected to one of said members 12, 15

by amovable part shiftable in the' -direction of movement of saidmember, arr-order to' .in which theforce is applied to said switchmember. 12.

In this embodiment of myinvention, the

. spring 22 is a tension. spring connected at one end to a bracket 23mounted on the insulating bar of the switch 12 midway between the knives13, 14, and at its other end to a coupling 22 which engages theeccentric or crank portion 24 of a rocking part or shaft 25 journaled inthe arms 18 of the operating member at a point remote from the-axis 19of said arms. The point of connection of the I spring 22 of the switchmember 12 or the bracket 23 thereof, moves in the space between theswitch contacts 7 7, and 8, 8.

The rocking part or shaft 25 moves in the direction ofthe operatingmember 15 and in a direction contrary 'to the movement of the switchmember 12, and the rocking of the shaft 25 is effected by any suitablemeans as an arm 27 rigidly mounted on the rock shaft 25 and extending inthe opposite direc tion from that of the crank portion 24, the arm 27having a lengthwise slot 28 therein through which a pin extends whichpin is carried by the bracket arm 17. Said pin is usually an extensionof the pivot 16. There is usually an arm 27 at each end of the shaft 25,and the extensions of the pivots l6 usually extend into arc shaped slots29 in the arms 18 of the operating member.

he throw of the switch member is limited by stop shoulders 30projectingfrom the brackets 17 into slots 31 formed respectively in theswitch blades 13, 14.

In operation, assume that the switch is off, that is, the parts are intheir position shown in Fig. 4. Upon the moving of the operating member15 to the left or anti-clockwise into the position shown in Fig. 1, thespring 22 is first tensioned due to the rocking move ment of the shaft25, and after the crank portion 24 of the shaft passes to the'left handside of the axis 16, the pull of the spring under, tension is thenapplied to the left 'on the switch member 12 andthe switch member causedto move in a clockwise direction on its pivot, engaging the knives withthe contacts 7, 7, 8, 8.

Movement of the operating member clockwise from its position shown inFig. 1 rocks the shaft 25 in the same direction first ten sioning thespring 22 and shiftingthe spring to the right hand sideof the axis16,'when the force of the spring 23 quickly moves the switchanti-clockwise bringing the knives 13, 14 out of engagement with thecontacts 7, 7, and 8, 8.

During the movement of the operating member 15, the arms 27 fulcrum onthe pivots 16 for the switch member, and owing to the slots 28'thereinare permitted to move endwise or radially relatively tothe pivots 16 asthe angle of said arms change. VVhen the crank 24 has moved far enoughso that the line of pull of the spring 22 moves from one side'as theright side. in Fig. 4 of the axis of the pivot 16 to the left sidethereof, the spring moves the switch 14 anti-clockwise or to the left,Fig. 4.

The arms 27 likewise fulcrum on the pivots 16 in the same manner duringthe movement of the operating'member 15 in a clockwise direction fromitsposition shown in Fig. 1 to that shown in Fig. 4.
